Counting pixels

This shot, made on beautiful Juliana, using the Hasselblad H3D-II 50, a 50 million pixels digital back, with the HC 100/2.2. resolving astonishing detail.
Is more pixels means better picture, not always, but often yes - provided the increase of pixels not made on compromising the dynamic range and noise level of the sensor. But does the client always need a bigger file for printing on virtually the same print advertising? Not really! But why more pixels welcome?
More details - it may not all resolved on the final print, but it is there, and because it is there, it allows the control over image more flexible. Retouch ?? Yes, it makes the retouch work a lot easier and faster, provided a fast enough compute to digest those pixels, but yes, it gives a much wider range of photo retouching, something photographer always try to avoid, something most photographers surrender to such needs.
